AWS Controllers for Kubernetes (ACK) lets Kubernetes users define AWS resources with Kubernetes custom resources. It periodically compares desired and actual AWS state and corrects drift. Documentation lists 74 service controllers, including S3, RDS, Lambda and DynamoDB. ACK supports declarative, version-controlled infrastructure alongside applications, across AWS accounts and regions. Read-only resources and read-only adoption support migration from other infrastructure-as-code tools. EKS users can install managed EKS Capabilities, where AWS handles controller installation and upgrades with automatic updates, auto-scaling and auto-tuning. Self-managed Helm installation runs on EKS, GKE, AKS, on-premises clusters and local environments, providing version and configuration control. AWS IAM authorizes controller access. Self-managed ACK costs nothing for Helm installation on Kubernetes 1.20+ on any Kubernetes cluster. EKS Capability pricing is hourly, with a base rate per enabled capability plus usage charges for each ACK resource managed.
